PORTABLE MAGNETO-ELECTRIC MACHINE.

Specification of Letters la'tent.

Patented Mar. 9, 1915.

Application filed February 19, 1912. Serial No. 678,477. 1

To all whom it may concern:

- Be it known that I, CONRAD KLEMMER, a subject of Czar Nicholas the Second of Bussia, and a resident of- Bisbee, county of Cochise, and State of Arizona, have invented a certain new and useful Improvement in Portable Magneto-Electric Machines, of which the following is the specification.

My invention relates to that class of lights which are designed for flash light purposes corresponding in use to the wellknown pocket search lights and has for its object to provide a lamp which will generate the current consumed by the light within itself, thereby eliminating the objectionable feature of the battery flash lights, to .wit: that of the battery becoming exhausted, so that when it is wanted the light is worthless.

I am aware that magneto generators have been made which are manually operated, but I am not aware of any machine which is constructed so as to be carried in the hand of the user as mine is intended to be, and in which all of the working parts are inclosed in a casing which not only protects them from dust, but insures perfect lubrication and has for its further object to use an essential element of the generating mechanism as a part of the inclosing case.

My means of accomplishing the foregoing may be more readily understood by having reference to the accompanying drawings, which are hereunto annexed and are a part of this specification, in which:

Figure 1 is a side view of my improved light, the outer cover being removed for the purpose of disclosing the interior construe tion. Fig. 2 is p a vertical sectional view "taken on the line m a: in Fig. 1.

Similar reference numerals refer to similar parts throughout the entire description.

As shown in the drawings, a horseshoe magnet 1, is provided to excite the field coils of the generator. This magnet constitutes the side walls of the inclosing case, all of the operative parts being within the said magnet, except one gear and pinion and the bearingfor the armatures. An armature 2 and pole pieces 3 of the usual or well-known type are associated therewith, the shaft of the armature being mounted in bearings 4 and 5 formed in lateral extensions 6 and 7 of the side plates 8 and 9. These plates, as will be apparent from an inspection of the drawings, serve to completely inclose the entire operative mechanism, thereby not only protecting them from dust and dirt, but effecting most efficient lubrication.

The shaft 10 of the armature 2 has mounted thereon a driving pinion 11, which meshes with a gear 12 carried by a shaft 13 which has mounted thereon a driving pinion 14, which meshes with a gear 15 suitably mounted upon a shaft 16, which has a pinion 17 mounted thereon, the pinion meshing with a gear 18 mounted upon a shaft 19, which carries a pinion 20, which isin mesh with the master gear wheel 21, which is rotatably mounted upon a shaft 22. This gear wheel is provided with a laterally extending hub 23 and has secured to it one end of a coil spring 24, which is located in an annular recess formed in the interior of a ratchet wheel 25, the other end of the coil spring 24 being secured to the annular rim 26 of the ratchet wheel 25 by means of a screw 27 or any other convenient manner.

28 is a pawl which is adapted to engage the teeth of the ratchet wheel and is carried by the lever 29, which ispivotally attached by means of a pin or pivot 30 to the end of the horseshoe magnet 1.

31 is a spring which operates to hold the lever normally in the position shown in Fig. 1.

32 is a detent adapted to prevent the ratchet wheel from moving in a reverse direction.

33 is the lamp which is mounted in a socket 34 of the usual or ordinary construction, suitable electric connections being provided to carry the current generated by the rotation of the generator 2 to light the lamp 33. The side plates 8 and 9 are secured together by means of screws.40, which are threaded into rods 41 located in suitable or convenient places, though any other convenient form of fastening may be employed which will insure a tight joint between the magnet and the side plates.

The operation of the device is as follows: The operator grasps the lever in his hand between the thumb and fingers and by C gear 21 and through the train of gears drives the armature 2 at a very high rate of speed. The operation is continued intermittently, thus maintaining a steady light for any desired length of time. In some places and at some times it may be found necessary to have a steady light without the necessity of manipulating the lever 29. I accomplish this by a brake arrangement, which is shown acting upon the shaft 13, which consists of a rod 35 slidably mounted in bearings 36. It is provided with a cutout portion or recess, asat 37, which is sufiicient to clear the shaft 13 when in normal position. The shaft 35 is-provided with a. head 38. By pressing upon this head or button 38 the shaft is moved inwardly, putting abrake upon the shaft 13. The lever 29 can then be operated until the spring 24 is wound up tight, when by pulling the pin out until the recess 37 clears the shaft 13, the action of the spring will furnish sufiicient power to rotate the gears for a considerable length of time, so as to furnish a clear light for some seconds without the necessity of pumping, and this light can then be maintained by an occasional application of power to the lever 29, the spring in the meantime acting as a booster, so as to maintain a clear light.

Having described my invention what I regard as new and desire to secure by Letters Patent is:

1. Agnechanism for generating electric currentlr adapted to be held in the hand and manually operated, comprising the combination of a horse shoe magnet, an armature and pole pieces located between its poles, side plates mounted on its sides, a train of gears adapted to rotate said armature, a spring which drives the master gear, a ratchet wheel journaled on the shaft which carries the master gear having an annular recess therein in which the said spring is located, one end of said spring being secured to the hub of the master gear, the

other end being secured to the ratchet wheel, a detent to prevent the reverse movement of said ratchet wheel, a lever pivotally attached to said magnet, a pawl, carried by the lever, which engages the teeth of the ratchet wheel, and a spring to hold said lever normally away from said magnet, all of said mechanism being located between the side plates,- which together with the magnet completely inclose said mechanism, whereby it is protected from dust and dirt. 2. A mechanism for generating electric current adapted to be held in the hand and manually operated, comprising the combination of a horse shoe magnet, an armature and pole pieces located between its poles, side plates mounted on its sides, a train of gears adapted to rotate said armature, a spring which drives the master gear, a ratchet wheel journaled on the shaft which carries the master gear having an annular recess therein in which the said spring is located, one end of said spring being secured to the hub of the master gear, the other end being secured to the ratchet wheel, a detent to prevent the reverse movement of said ratchet wheel, a lever pivotally attached to said magnet, a pawl, carried by the lever, which engages the teeth'of the ratchet wheel, and a spring to hold said lever normally away from said magnet, a brake for said train of gears to hold them from said rotation, all of said mechanism being located between the side plates, which together with the magnet completely inclose said mechanism, whereby it is protected from dust and dirt.

In testimony whereof I have signed the foregoing specification. I
